Open-wheel car - online puzzles

An open- wheel car (formula car, or often single-seater car in British English) is a car with the wheels outside the car 's main body, and usually having only one seat. Open- wheel cars contrast with street cars, sports cars, stock cars, and touring cars, which have their wheels below the body or inside fenders. Open- wheel cars are usually built specifically for racing, frequently with a higher degree of technological sophistication than in other forms of motor sport. Open- wheel street cars, such as the Ariel Atom, are very scarce as they are often impractical for everyday use.
